SPRAY-NozzLE.

Specification of Letters Patent.

Patented July 23, 1912.

` Application led February 12, 1912. Serial No. 677,138.

To all whom 'it may concern:

Be it known that I, FREDERICK G. MAN LY. a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinols, have invented certain new and useful Improvements in Spray-Nozzles, of which the following is a specification.

The device of the present invention relates to a nozzle adapted to break a stream of fluid passed therethrough into spray for the purpose of distributing said Huid in the form of fine particles over a relatively large The objects `of the present inventionI are to produce a nozzle for accomplishing the above result which is cheap and simple as well as strong and durable of construction, and which will so deflect and break up the streams of fluid as to produce a sheet of spray which will cover all the surface intended; that is to say, the spray when projected will'be in such form that upon striking the surface upon which it is to be deposited it will entirely cover said surface. It will not simply fall upon the edges of said surface, but will cover the entire surface, thereby obviously increasing the edectiveness of the'spray.

Further objects of the invention are to produce a nozzle which can be easily kept clean; which will be capable of operation under varying degreesl of pressure; and which can be used under conditions where heat is present without danger of becoming cracked or otherwise mutilated by the eX- pansion and contraction which necessarily takes place in devices subject to unusual heat influences.

The invention further consists vin the features of construction and in the combination of 'parts hereinafter described and claimed.

In the drawings, Figure 1 is a view, partly in section,'showin g the spraying appliance of the present invention in operative position; Fig. 2, a vertical section of the spraying appliance; Fig. 3, a section taken on line 3-3 of Fig.' 2, looking in the direction of the arrow; and Fig. 4, a section on line 4-4 of Fig. 2, looking in the direction of the arrow.

For the purpose of illustrating one application of my invention, I haveillustratedit in connection with an oil receptacle 5 of a type used in conjunction with the carbureter of a gas furnace. However, it is not the intention to in any wise limit the use of the spray to this particular mechanism, although it possesses certain structural features which especially adapt it for usage with such a mechanism. It may, however, be readily used in other fields without departing from the spirit of the invention. The receptacle 5 is provided with a screw-threaded upper opening 6, into which is entered a supply pipe (not shown) for conduct-ing liquid to the receptacle; and said receptacle, at its lower end, is provided with an interiorly screw-threaded surface 7 but the present invention, as previously stated, is notat all limited to a usage in connect-ion with such a form of receptacle.

The sprayin nozzle of the present invention consists o a body portion 8, comprising an upper or head-like portion 9, and a lower or fiange-like portion 10. The flange-like portion may be congured,.as clearly shown in Figs. 1, 3 and 4, to form a nut to which a tool can be applied for the purpose of fastening or loosening the spraying nozzle from the device towhich it is attached. The headlike portion 8 terminates in an offset portiongage the screw-.threads on thel surface 7.

And the body portion is provided with a centrally located discharge opening 12, which, in the form illustrated, is of a conical formation. An upper or inner series of ducts or passages 13, and a lower or outer series of ducts or passages 14 lead into this central discharge opening 12. The upper series of ducts 13 is more clearly illustrated in Fig. 3, and, as will be seen from a `study of this figure, said ducts are arranged in radial alinement with the center of the opening 12. By this arrangement, the streams of liquid forced through these ducts or passages 13 and discharged into the central opening 12 will collide or impact with one another at a point approximately the center of the opening 12; and by such collision or impact these streams will be broken into spray, which will fall downwardly and be `discharged through the center of the opening 12.

The ducts or passages 14 are more clearly illustrated in Fig. 4, and, as will be seen from Fig. 2, the ducts or passages 13 are `which naturally take place.

arranged to permit the fluid to' enter these passages at a point above the offset 11, whereas the lower openings 14 extend through this offset portion, and in order to permit the fluid to enter these passages 14, cross passages 15 are provided, extending transversely through the offset portion 11 and communicating with the ducts or passages 14. Referring again to Fig. 4, it will be seen that the ducts 14 are arranged out of radial alinement with the center of the opening 12, and they are so arranged with respect to one another as to give a whirling movement to the streams of liquid passing therefrom into the opening 12; that is, they direct the streams toward the sides of the opening rather than toward the center, and the streams are thus deflected so as to follow the walls of said opening. These Walls being of circular formation, said streams will naturally be given a whirling or rotative movement, which will break them into spray and tend to force or throw them outwardly from the center of the opening 12, so that when finally discharged from said opening, they will be in the form of a circle.

As heretofore explained, the liquid coming through the openings 13 will be discharged downwardly at the center of the opening 12, and the liquid coming-through the openings 14 will be discharged around the walls of the opening 12. In this man? ner the' two streams of liquid when broken into spray will produce a mass of spray of circular formation. Obviously, if the openings 14 alone were utilized, the spray discharged would be in the form of a hollow ring. If the openings 13 alone were utilized, the spray discharged would be in the form of a relatively small circle. By utilizing the two sets of openings in conjunction with one another, the discharge from the openings 14 form the outline of a discharged mass of spray, while the discharge from the openings 13 fill in the interior thereof, thus effecting the discharge ,of a complete and unbroken mass of spray.

By referring to the drawings, it will be noted that all of the openings or conduits are of a nature whereby they may be easily cleaned and can be made\of suiicient diameter so that the danger of their becoming choked is avoided; and, furthermore, the

movements given to the streams of liquid are sufficient to break them into spray even though the pressure upon the liquid may be comparativel light.

As hereto ore stated, the present invention is particularly designed and adapted for use in connection with carbureters used upon gas furnaces, and when employed for such usage the formation is particularly adapted to withstand, without material damage, the expansion and contraction It will be noted that the head 8 is of a substantially thick and solid nature. Hence this head will, for a considerable period of time, remain in a relatively cool condition, and the oil striking this head and flowing over it will become more or less cooled, so that upon reaching the offset 11, it will not be in such a heated condition as to cause a sudden expansion of the metal at this `point and consequently a breakage.

The device may be easily removed to permit of the substitution of a different form of spray, if desired; and by changing the configuration of the central opening 12, the figure described by the projected spray can be varied, so as to allow the projected spray to cover a restricted or wide area, as desired.

In Fig. 1, I have illustrated a strainer 16, which may be employed with the device if desired, such an application being especially desirable in case the liquid being treated is of a muddy or dirty nature.
